there are a few  things about ivory soap that i like and one of them is that it actually floats. So when you or your kids are taking a bath and you drop the soap in your bubble bath you will be able to find it cause it will be floating on top of the water. it is  also fragrance free. I haven't tried all types of ivory soap bars but the white bars the plain ivory actually does float a co worker of mine advised me of this information so I went to the store and bought some so I could test and it actually float. thumbs up
